Abstract

Finding₂ a renewable, cleaner and inexpensive source of energy has been a momentous challenge to the researchers. Among others, one intriguing solution is molecular H₂ which is considered as an ideal energy source for the future needs. Obtaining H₂ is extremely appealing but difficult to achieve. One of the most viable solutions is the electrocatalytic hydrogen evolution reaction (HER). In this paper, we presented electrocatalytic HER performances of pyridoxal-semi carbazone (PLSC) and pyridoxal S-methyl-iso-thiosemicarbazone (PLITSC) stabilized Co(II) and Co(III) complexes, i.e. ([Co(PLSC)(SO₄)(H₂O)₂], 1) and [Co(PLITSC-H)(PLITSC-2H)].CH₃OH, ₂)). Both complexes catalyzed the HER in acidic media while complex 2 was found to be more active than complex 1.
